Title: Oil leakage detecting device for hydraulic construction machine
Inventor: OOWADA YOSHINOBU
IPC: G01M3/26
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To surely detect an oil leakage from a hydraulic equipment or piping constituting a hydraulic circuit in its early stage. SOLUTION: A level sensor 23 for detecting the level height of a hydraulic fluid tank 13 is connected to a hydraulic fluid quantity change detecting means 24 to operate the hydraulic fluid quantity change detecting means 24 in interlocking with a key switch 26. When a prescribed time has passed after OFF of the key switch 26, the signal, from the level sensor 23 is fetched into the hydraulic fluid quantity change detecting means 24, and when the key switch 26 is ON, the time and the level height position of the hydraulic fluid tank 14 are read from a timer 24c and the level sensor 23, respectively, and the level height change within the hydraulic fluid tank 13 is calculated while a hydraulic shovel is rested to detect an oil leakage. When the oil leakage is present, an oil leakage alarm is given by an alarm means 25 consisting of a buzzer 5a and a lamp 25b.

Title: Waveform interpolating voice coding using spline
Inventor: SHOHAM YAIR
IPC: H03M7/30
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To reduce complicatedness, and perform low bit rate voice coding by synthesizing a regenerative signal by interpolating time of a spline display to convert a time area of first and second aggregation of a frequency area parameter. SOLUTION: In a block 31, the size of a fixed cardinal number 2 is secured by padding an input spectrum with zero. Afterwards, in a block 32, spline transform is performed, and in a block 33, IFFT generated as a result is performed. A block 34 is used to preserve respective aggregation of data generated as a result so that a spline factor is interpolated (like a block 38) on the basis of a waveform of the present and the past. A block 36 normalizes dynamic time by performing an operation on a numeric value of a present input pitch and a numeric value of a past input pitch preserved in a block 35, and in a block 37, the spline factor interpolated in the block 38 is decided on the basis of it. Finally, in a block 39, a tertiary spline is interpolated, and as a result, an output voice waveform is generated in a 'time area'.

Title: Oil feeding equipment
Inventor: MASAI SHIRO
IPC: B67D7/28
Filed: 1989-03-13
Abstract: PURPOSE:To perform an integral number oil feed continuously without stopping the oil feed operation by a method wherein a control unit, which stops an oil feed at the last stage of oil feed at the zero in case the liquid level is detected when the number of a digit which is made to be zero at the time of completion of the oil supply falls on at least two digits which are close to zero, is provided. CONSTITUTION:The title equipment has a control unit 14, which stops an oil feeding at the last stage of the oil feeding at the zero point in case the liquid level is detected when the number of a digit which is made to be zero at the time of completion of the oil feed falls on at least two digits which are close to zero. In this case, when the liquid level is detected when a number at the second place of decimals falls on at least two digits which are close to (0), e.g., (7) to (9), the oil supply is stopped at the following (0). Therefore, even when the liquid level is detected during (0) to (6), unless the level sensor is not detecting the liquid level on at least two numbers among (7) to (9), the oil feeding is continued starting from (0), (1)... again. By this method, even when the liquid level descends, e.g., by releasing of air in the air reservoir during an oil feeding work, the oil feeding is continued to a complete (full tank) condition wherein the liquid level is detected by the level sensor, and also, an integral number oil feed can be performed.

Title: Switching method for common bus line
Inventor: KOYAMA MASAYUKI
IPC: G06F15/16
Filed: 1986-03-18
Abstract: PURPOSE:To avoid wrong access of a common memory by switching a command bus line after inhibiting the generation of a bus access permitting signal when a switch indicating signal is produced. CONSTITUTION:When an active processor 1 has a fault, a switch indicating circuit 3 outputs automatically or manually the switch indicating signal to a bus access control circuit 19 via a signal line 17. Then the circuit 19 inhibits all permitting signals except for that of an IO device that is allowed to use a common bus line. Furthermore, said allowed permitting signal is also inhibited when no bus use request is delivered any more. Thus a bus switch signal 18 is outputted to a bus switch circuit 8 after the bus access of all IO devices is inhibited. Then the common bus line is switched.
